Skyscraper 4D is a new breed of tower building game that lets you design large, complex buildings with remarkable ease. In this game, you'll serve as architect, engineer, and real estate developer, all at the same time, as you accumulate money and expand the reach of your real estate empire. You'll control everything from the shape of your buildings, to the placement of columns, walls, elevators, balconies, kitchens, furniture, and more. The tedious work normally associated with construction has been totally automated, letting you focus on the creative side of things! Skyscraper 4D is easy to pick up, but it strives to stay as close to reality as possible. That means whatever you design needs to be structurally and economically sound. But not to worry, if you run into trouble there are plenty of nifty warning indicators to help you shore things up. If you like to build things, you've come to the right place! ============================== Key Features: • Open World Sandbox Game: Construct as many skyscrapers as you want, in a massive, unrestricted city. • Total Design Control: In this game, you won’t simply position buildings, you’ll get to design every aspect of the building, including its shape, height, materials, floorplan, and more. • Intuitive Tutorial: We’ve created a simple and intuitive tutorial to make Skyscraper 4D as easy to learn as possible. No prior building design experience is required! • Floorpan Tool: You can easily add walls, doors, bathrooms, kitchen appliances, balconies, furnishings, and more to create the floorplan you want. • Mirroring Tool: We’ve created a tool that lets you quickly design symmetrical buildings by mirroring all of your design actions across the x and/or y-axis of your grid. We also offer an option for mirroring your build actions in a triangular fashion. You can even use them both at the same time! • Bézier Curves: Easily add curved windows or walls to give your building a unique shape. Just tap on the Bézier Curves button in the build menu. • Helpful Warning Indicators: When you design something structurally unsound, we’ll show you a warning indicator that will explain the problem clearly, and give you options to help resolve the issue quickly. • Performance: Skyscraper 4D was built using the Metal API for graphics, allowing us to deliver incredible realism and performance. Every aspect of the game has been tightly optimized to ensure amazing responsiveness, smoothness, and loading times across a wide range of devices. • Realism: We’ve tried to make Skyscraper 4D reflect the real world. Everything from the visuals of the city (which are loosely based on Manhattan), to the structural and financial components of the game, are intended to mimic reality as closely as possible. • Soundtrack: We’ve picked out a nice selection of soothing but exciting songs to help keep you in the zone. • On-Demand Resources: We’ve kept the initial app download nice and small to avoid wasting space on your device. When you open the game on Wi-Fi, we’ll download a few asset packs in the background to enrich the game experience with music and sharper detail. • No Ads or Endless Wait Times: You won’t need to do a ton of busy work for no reason, or wait ages for money and resources to accumulate. • Feedback Welcome: We are always looking to improve, and we’d love to hear your feedback! We’ve included a feedback button right inside the game in case you’d like to message us. Alternatively, feel free to send us an email at info@skyscraper4d.com.

TRUSSFALL is bridge engineering, no shortcuts. Build and stress-test real bridge designs across 99 engineering trials. Place beams, add cables, and triangulate trusses — then send a car, truck or mega-rig across to see if your structure holds. Four materials unlock as you advance: - Wood — cheap, low strength, good for short spans - Steel — your workhorse: strong, stiff, balanced - Cable — tension-only; build suspensions and cable-stays - Reinforced concrete — heaviest, strongest, end-game Build your truss. Run the live load. Watch a vehicle roll across. If your design holds, you earn stars. If your weakest joint snaps under tension, gravity wins. EVERY LEVEL PLAYABLE FROM DAY ONE All 99 trials are free to play. The Lifetime Unlock removes the hint paywall (3 free hints per game), grants unlimited hints, and reveals all engineering-accurate bridge templates. Optional hint packs available too. WHAT'S INSIDE - 99 engineering trials with progressive difficulty - 10 distinct biomes with unique terrain features - 4 materials with realistic structural properties - Warren, K-truss, Pratt, suspension, cable-stay, arch templates - Live load simulation with stress-tested physics - 3 free hints; Lifetime gives unlimited - Family Sharing supported (Lifetime only) - 100% on-device data — zero tracking, zero ads, no accounts ENGINEERED FOR THE PATIENT Truss math is computed live. Joints carry real loads. Members have real strength limits. Cables can only pull, never push. These are the same principles a civil engineer uses — and the level designs reward thinking like one. If you've played Bridge Constructor or Poly Bridge and wanted something with more engineering depth, this is for you. PRIVACY-RESPECTING BY DESIGN No analytics. No third-party SDKs. No data collection. Your progress lives on your device. Always. Built by a single developer who couldn't find the engineering puzzle game he wanted to play.
